How are antibodies and antigens related?

Antibodies and antigens are closely related components of the immune system. Antigens are foreign substances, such as bacteria or viruses, that trigger an immune response, while antibodies are specialized proteins produced by the immune system to recognize and bind to specific antigens. This binding helps neutralize or eliminate the antigens, playing a crucial role in protecting the body against infections. Essentially, antibodies act as the body's defense mechanism against the threats posed by antigens.
